Abstract: The amino acids content of milk of Brown Carpathian cattle (n = 13) of Ukraine was studied. Cows were selected on different altitude, at meadows with different plant content and different peculiarities of mountainous climate. The results of this investigation on local breed were compared with results of cows of commercial Holstein breed. Amino acids detection was done by the method of ion-changing columnar chromatography. Cows of local for Transcarpathian region of Ukraine Brown Carpathian cattle exceeded Holstein breed on the majority of amino acids (on 11 out of 17 investigated), including indispensable valine (by 1%), threonine (by 0.09%), lysine (by 0.55%), leucine (by 0.60%) and dispensable glutamine (0.55%). Methionine, cysteine and proline were higher in the milk of Holstein Red-and-White breed, by 0.03%, 1.83% and 1.98% accordingly. The tendencies became the same when the cattle of different breeds but in the conditions of one village were compared.
